Dear Sai,

You first need to define events and extract them as epochs.

Then 'Plot' -> 'ERP map series' - 'In 2D' to show scalp topography.

These are the basic visualization ability available from GUI. If you can
code, you have much more degrees of freedom.

> *Hi Everyone,*
> We are working on changes in the local field potential in hippocampus of
> rats after drug treatment. The study protocol involves stimulating nPO
> region with current ranging from 20 to 120mA, and recording EEG from CA1
> region of hippocampus. Stimulations will be given 6s with 250Hz frequency
> for every 100s.
> We are beginners for Matlab and EEGLab, need your help in generating the
> following graphs
> 1. We want to generate heatplot for a period covering 5s pre stimulus, 6s
> stimulation and 5s post stimulation period by taking pre-stimulus as a base
> line. The same will be generated for average of 5 to 10 stimulations
> periods.
> 2. Over a period of 2hours of study we will be having 72 stimulation
> periods. We want to generate Heatplot for 72 stimulations (5s period of
> each stimulation, 1st sec will be excluded for stimulation artifact
> removal) by taking first 18 as baseline. The same will be generated for
> average of 6-8 animals.
> we are able to generate heatplot for single stimulation period using
> EEGlab but generating graph by taking average of multiple stimulations was
> difficult for us, can anyone help us in generating the above mentioned
> Heatplots?
